Indigenously Developed Robotic Devices for Inspection of Critical Components in Power Plants

Abstract

The growing global population, combined with rapid industrialization and rising living standards, has resulted in a substantial increase in energy demand. This trend necessitates the development of innovative energy technologies that align with environmental protection policies. As a result, many newly constructed power plants are increasingly utilizing renewable energy sources or cogeneration methods. This dynamic energy landscape has introduced new challenges, as numerous coal plants have transitioned to flexible operations to accommodate the fluctuating availability of renewable energy. To ensure a reliable and uninterrupted electricity supply, power generation utilities must prioritize the reliability of their equipment and systems. The incorporation of robotics into power plant operations and maintenance is emerging as a key solution to address these challenges. While several utilities are utilizing third-party robotic technologies, there remains considerable scope for the development of indigenous solutions. NETRA, R&D wing of NTPC; the largest power utility of India, has taken significant steps toward developing such tools indigenously. As part of these efforts, NETRA has successfully developed multiple tools, including two developed in collaboration with CMERI, Durgapur. These tools have been effectively deployed across various power plants which demonstrate strong potential for future commercialization within the industry. This paper delves into these advancements and their implications for the sector.
